A new report from United Nations scientists claim people are to blame for global warming.

The Inter-governmental Panel on Climate Change has looked at data since the 1950s. They say the earth has changed in "unprecedented ways" since then and they are more confident than ever that humans are to blame.

Research also states that the earth has stopped warming over the last 15 years.

However, the IPCC report says the recent slowdown of warming cannot yet be considered a long term trend.

Why are we being told we're facing a global warming crisis when the earth hasn't gotten warmer in the last 15 years? Joe Bastardi, chief forecaster at Weather Bell, answers this and more, on CBN Newswatch, Sept. 27.
